IMPROVEMENT lN BRICK-DRYING HOUSES.

Specification forming part of Letters Patent No. 125,013, dated March26, 1872.

I, GEORGE G. BOVEY, of Cincinnati, Hamilton county, Ohio, have inventedan Improved Drying House, of which the following is a specification Thisinvention relates to a house which has been designed for the purpose ofevaporating the moisture from newly made bricks before they are placedin the kiln and which comprises an arrangement of furnaces, flues,registers, inclined tracks, and movable trucks, whose details ofconstruction and operation I will now proceed to describe.

Figure l is a transverse section of a dryinghouse embodying myimprovements, one half of the house being shown as filled with brick andin operation, while the other half is empty and in condition forreceiving brick. Fig. 2 is a longitudinal section of the same withportion of the house broken away; and Fig. 3 is a plan of the house andits accessories.

The house or dryin g-chamber proper consists essentially of walls A,floor B, ceiling G, and roof D, of which the walls, floor, and ceilingshould be made of materials that will resist the heat radiating from thefurnaces. Running longitudinally of the building are a number of piers,E, which are carried up about half way to the ceiling, and these piersserve to support tracks F, which incline toward the deliveryend of thehouse, as seen in Fig. 2. Adapted to traverse these tracks are theflanged wheels G of trucks H, upon which the newly-made bricks arehacked. It is preferred that the bottoms of these said trucks should beperforated, or else made of iron bars a suitable distance apart from oneanother, so as to allow the heat to circulate freely around the bricks.Built into the walls A, and also into one or more of the piers E, arefurnaces I, whose tops, sides, and inner ends are perforated at 17, andsaid furnaces are provided with doors J that are external to the house.These furnaces are provided with ash-pits K, having doors is. Ar rangedtransversely of the building, and beneath the floor B, is a flue, L,whose discharging-end communicates with the chimney M, and the bottom ofthis flue inclines toward said chimney, as shown in Fig. 1. The floor Bis pierced at suitable intervals with openings 1) I that communicatewith the subterranean flue L, and these openings are furnished withhinged dampers or registers N. The registers N are capable of beingopened or closed by means of rods 0, which project through the walls A,and said rods are provided at their outer ends with handles 0. 1- is acatch-basin or cistern, into which all the water of evaporation isconducted by flue L. If preferred, the upper part of the house can bedivided into two equal portions by the longitudinal partition B, therebyallowing either half of the drier to be used independently of the otherhalf, or alternately therewith but in this case it will be necessary toprovide said partitions with shutters S that can be opened when theentire building is to be used, so as to establish a perfect circulationof air within it. The ends of the house are provided with doors T thatare large enough to admit the trucks with their loads of bricks. Pits Ufacilitate the feeding of the furnaces and attention to the damper rods.

The operation of drying .bricks within this house is carried on in thefollowing manner: The newly made bricks are first properly hacked uponthe trucks H, and the latter are then shoved upon the elevated ends oftracks F, and allowed to descend the incline until they reach thelowermost end of the same, where their further progress is arrested.()ne truck after another is thus placed in the building until it isfilled, when the doors T are closed and fire is started inthe furnacesI. The fire, smoke, and heated gases emanating from the furnaces ascendand completely envelop and circulate around the bricks, and the resultis that the latter are thoroughly and uniformly dried in a short time,and in the most economical manner.

As there are no openings or other outlets in the ceiling for the escapeof heat, all the prod nets of combustion are compelled. to descend andescape through the opening 1) into the flue L, as indicated by arrows inFig. 1. These openings not only serve as outlets for the smoke from thefurnaces, but they also allow all the water of evaporation, thatnaturally falls to the floor, to escape into flue L, which conducts saidwater into the catch-basin P. Whenever it is desired to retain the heatwithin the build-' ing for any length of time, the dampers N are closedas long as necessary, and by opening or partially opening them, thetemperature of the drier can be lowered to suit circumstances. All themoisture having been evaporated from the bricks by the above-describedprocess, the fires in the furnace are drawn, the doors of the houseopened, and the trucks allowed to run out at the lowermost end of theincline. In the meantime, the other half of the furnace, having beencharged with bricks and fuel, may be set in active operation for burninganother batch.

In the drawing the furnaces are represented as being made of metal, butit is evident that they may be constructed of brick, a sufficient numberof the latter being omitted at intervals so as to leave openings for theescape of heat into the interior of the house.

The perforated furnaces, by allowing the flames to escape therefrom, addgreatly to the economy and efficiency of the apparatus, and enable thedrying of bricks with much less fuel than could be done if said furnaceswere im perforate.
